Abstract: Disclosed is a vehicle jack device. The vehicle jack device according to an exemplary embodiment of the present invention includes: a base portion in which an inserting hole into which a hinge shaft is inserted is formed and which is supported on a bottom side; a pair of lower arms of which a first portion is installed in the hinge shaft of the base portion in a rotatable way and in which a reinforcing rib is formed in a lengthwise direction; a pair of upper arms respectively installed in a second portion of the lower arm, and on which a reinforcing rib is formed in a lengthwise direction; a bracket member for fixing a first portion of the upper arm in a rotatable way; and a driver installed between the lower arm and the upper arm and providing a tucking driving force to the lower arm and the upper arm.

Abstract: A plasma display driving apparatus and a driving method thereof are provided. The plasma display driving apparatus includes a panel formed with a scan electrode, a sustain electrode, and an address electrode; and a driver for varying a rising time or falling time of sustain pulses applied to at least one of the scan electrode and the sustain electrode when the same image is repeatedly displayed in the panel during at least two frames. The driving method of a plasma display driving apparatus includes applying data pulses to an address electrode during an address period; and applying sustain pulses to at least one of a scan electrode and a sustain electrode during a sustain period, wherein a rising time or falling time of sustain pulses applied during the first frame is dissimilar to a rising time or falling time of sustain pulses applied during the second frame when the same image is repeatedly displayed in the panel during at least two frames.
